Abstract
A grooving sled for use with a pre-formed groove blade and hot knife, for making grooves in expanded polystyrene foam boards or walls. The grooving sled includes a built-in straight edge guide, one of two cutting position margins, and a stabilizer plate that fits inside a freshly-cut groove to keep the grooving sled straight while operating along the cutting layout line established on the board or wall. The stabilizer plate aligns with the groove blade by use of an angular adjuster, and if necessary, an insert bar. The stabilizer plate can also be adjusted vertically.
Claims19
A grooving sled for making a groove in a foam insulation board, said grooving sled comprising:
- a) a hot-knife holder;
- b) a straight edge guide;
- c) a frontal edge perpendicular to said straight edge guide;
- d) a first blade holder for receiving a first end of a groove blade, said first blade holder being fixed proximally to said straight edge guide and fixedly located along said frontal edge for providing a cutting margin from said straight edge guide;
- e) a second blade holder for receiving a second end of said groove blade, said second blade holder being distal to said straight edge guide and adjustably located along said frontal edge, wherein said second blade holder is fixable in a position along said frontal edge;
- f) a stabilizer plate, with a portion thereof extending below an anterior surface of said grooving sled, said portion insertable into a groove formed by said groove blade during operation of said grooving sled;
- and
- g) alignment means for aligning said stabilizer plate with said first end of said groove blade, said alignment means comprising:
- i) an angle adjuster mounted adjacent to said straight edge guide, said angle adjuster angularly adjustably supporting said stabilizer plate for angular alignment of said stabilizer plate with an angle of said first end of said groove blade;
- and
- ii) an insert bar;
- wherein said stabilizer plate is mounted adjacent to said angle adjuster, or mounted in between said adjuster and said insert bar.
A grooving sled for making a groove in a foam insulation board, said grooving sled comprising:
- a) a hot-knife holder;
- b) a straight edge guide;
- c) a frontal edge perpendicular to said straight edge guide;
- d) a first blade holder for receiving a first end of a groove blade, said first blade holder being fixed proximally to said straight edge guide and fixedly located along said front edge for providing a first position for a cutting margin at ½ inch from said straight edge guide, and a second position for said cutting margin at 1 inch from said straight edge guide;
- e) a second blade holder for receiving a second end of said groove blade, said second blade holder being distal to said straight edge guide and adjustably located along said frontal edge, wherein said second blade holder is fixable in a position along said frontal edge;
- f) a stabilizer plate, with a portion thereof extending below an anterior surface of said grooving sled, said portion insertable into a groove formed by said groove blade during operation of said grooving sled;
- and
- g) alignment means for aligning said stabilizer plate with said first end of said groove blade, said alignment means comprising:
- i) an angle adjuster mounted adjacent to said straight edge guide, said angle adjuster angularly adjustably supporting said stabilizer plate for angular alignment of said stabilizer plate with an angle of said first end of said groove blade;
- and
- ii) an insert bar;
- wherein said stabilizer plate is mounted adjacent to said angle adjuster, or mounted in between said angle adjuster and said insert bar.
